* fhandler.cc (fhandler_base::has_ongoing_io): Define new function.
(fhandler_base::read_overlapped): Use has_ongoing_io to avoid writing when
handle has not completed last I/O.
(fhandler_base::write_overlapped): Ditto.
* select.cc (peek_pipe): Be more careful about accessing hEvent field from
get_overlapped().
value.
(get_ipv4fromreg_ipcnt): New static function to fetch number of
configured IPv4 addresses for a given NIC from registry.
(get_ipv4fromreg): New static function to fetch configured IPv4
addresses for a given NIC from registry.
(get_friendlyname): New static function to generate friendly name.
(get_hwaddr): New static function to copy hardware address.
(get_xp_ifs): Restructure slightly. Add code to generate IPv4 entries
entries for interfaces which are disconnected.
* fhandler.cc (fhandler_base::fcntl): Fix comment.
(fhandler_base::wait_overlapped): Accept an optional len parameter. Use the
len parameter when WriteFile fails with ERROR_IO_PENDING. Make debug output
less alarming.
(fhandler_base::write_overlapped): Pass len to wait_overlapped.
* fhandler.h (fhandler_base::wait_overlapped): Add an optional argument
denoting the number of characters intended to be written.
* fhandler_tty.cc (fhandler_pty_master::close): Don't close archetype handles
when cygwin is still initializing since the handles aren't actually opened at
that point.
writes. Don't reset event handle when we see a ERROR_IO_PENDING.
* sigproc.cc (stopped_or_terminated): Use bool constants for consistency.
* wait.cc (wait4): Remove nonsensical comment.
"override" entries.
(from_fstab_line): Handle mount points same as Cygwin itself. Use
"cygdrive prefix" as posix name of cygdrive prefix.
(from_fstab): Add auto entries for /usr/bin and /usr/lib. Add
MOUNT_AUTOMATIC and MOUNT_IMMUTABLE flags to default root dir entry.
Use "cygdrive prefix" as posix name of default cygdrive prefix.
(getmntent): Allocate smaller buffers. Align output closer to output
of mount(1).
* fhandler_proc.cc (format_proc_uptime): Use global system_info rather
than retrieving a local copy of the SYSTEM_INFO. Drop call to
GetSystemTimes and retrieve SystemPerformanceInformation on all systems
again with buffer size big enough for 64 bit systems.
(format_proc_stat): Use global system_info rather than retrieving a
local copy of the SYSTEM_INFO. Retrieve SystemPerformanceInformation
with buffer size big enough for 64 bit systems.
* fhandler_proc.cc (format_proc_uptime): Use GetSystemInfo to retrieve
processor count. Use GetSystemTimes when available to retrieve system
idle time. Improve debug output.
(format_proc_stat): Use GetSystemInfo to retrieve processor
count. Improve debug output. Ignore if SystemPerformanceInformation
returns error. Explain why.
(init_cygheap): Inherit locale field via mini_cygheap.
* cygheap.cc (cygheap_at_start): Define new variable.
(cygheap): Initialize as cygheap_at_start so that locale information is always
available.
(cygheap_init): Initialize cygheap iff it is set to cygheap_at_start.
* shared_info.h (memory_init): Accommodate argument change.
* memory.cc (memory_init): Accept an argument indicating whether cygheap should
be initialized or not.
* dcrt0.cc (child_info_fork::handle_fork): Pass false to memory_init().
(child_info_spawn::handle_spawn): Ditto.
(dll_crt0_0): Pass true to memory_init when not forking or execing.
* cygheap.h (cygheap_types::HEAP_2_DLL): New enum.
* dll_init.h (dll): Remove unused namelen field.
(dll_list::load_after_fork): Accommodate change in arguments.
* dll_init.cc (dll_list::alloc): Allocate dll information in the cygwin heap.
(dll_list::detach): Free dll information from the cygwin heap.
(dll_list::load_after_fork): Use dll information in the cygwin heap directly
rather than querying parent.
* fork.cc (frok::first_dll): Delete.
(frok::child): Don't report on first_dll. Don't pass it to load_on_fork.
(frok::parent): Don't set first_dll.
(fork): Ditto.
object. Explain why. Drop call to GetSystemInfo, rather call
getpagesize to get allocation granularity. Only align to allocation
granularity under WOW64. Use roundup2 to align.
(dll_list::detach): Call NtUnmapViewOfSection instead of VirtualFree.
* dll_init.cc: Fix formatting.
(dll_list::alloc): Only allocate as much memory for struct dll as
necessary for given DLL name.
(dll_list::load_after_fork): Only read a single page of parent memory.
Only read more if namelen indicates that it's necessary.
(set_clipboard): Add basic error checking. Set errno here. Per MSDN,
don't call GlobalFree on data block transferred to clipboard.
(fhandler_dev_clipboard::write): Drop setting errno after call to
set_clipboard.
(fhandler_dev_clipboard::read): Add basic error checking. Simplify code.
